IPN "INVALID" response issue in Coldfusion

IPN INVALID RESPONSE ISSUE IN COLDFUSION
I have faced an issue when I use CFHTTP tag in coldfusion to get validity response from paypal about data. In Coldfusion I get an INVALID response from paypal. And this issue in coldfusion persist for some of the payments, not in every case.
But when I use the same link to hit through php curl, I get “VERIFIED” in response content.
The URL I use to send to paypal is given below:
http://www.paypal.com/cgi-bin/webscr?cmd=_notify-validate& mc_gross=5.00&protection_eligibility=Eligible&address_status=confirmed&payer_id=SS3F4FDSRYFJ4&address_street=1219+Vernon+St.&payment_date=20%3A08%3A46+Mar+14%2C+2021+PDT&payment_status=Completed&charset=windows-1252&address_zip=54720&first_name=McKenna&mc_fee=0.45&address_country_code=US&address_name=McKenna+Hoff&notify_version=3.9&custom=22744&payer_status=verified&business=orders%40afi-usa.com&address_country=United+States&address_city=Altoona&quantity=1&verify_sign=Ai9pZWO7HELsWF2nYCZXKt9ryPoRAzwhGlFmEofj4cBTZG8k5ZJCV5zB&payer_email=smithcocandlesLLC%40gmail.com&txn_id=6623965058049454H&payment_type=instant&payer_business_name=Smith+%26+Co.+Candles+LLC&last_name=Smith&address_state=WI&receiver_email=sean%40afi-usa.com&payment_fee=0.45&shipping_discount=0.00&insurance_amount=0.00&receiver_id=EBMDNRZ7J4AGL&txn_type=web_accept&item_name=F21035%2Csample%7CF22983%2Csample%7CF20916%2Csample%7CF21778%2Csample%7CF20615%2Csample%7CF22922%2Csample&discount=0.00&mc_currency=USD&item_number=&residence_country=US&shipping_method=Default&transaction_subject=&payment_gross=5.00&ipn_track_id=6372115d45d80
